hemimorphic
hemimorphic, a. Cryst. (hɛmɪˈmɔːfɪk) [f. hemi- + Gr. µορϕή shape + -ic.] Of a crystal: Having unlike planes or modifications at the ends of the same axis. So hemiˈmorph, a hemimorphic crystal. hemiˈmorphism, the property of being hemimorphic. hemiˈmorphous a. = hemimorphic. ˈhemimorphy = hemimorphis...

hemimorphite
hemimorphite Min. [f. as prec. + -ite.] Kenngott's name (1853) for hydrous silicate of zinc, the crystals of which are hemimorphic. Now generally used in place of earlier names such as calamine.1868 J. D. Dana Syst. Min. (ed. 5) v. 409 Unfortunately, Brooke & Miller, in 1852, reversed Beudant's use ...

Pyrargyrite
Both crystallize in the ditrigonal pyramidal (hemimorphic-hemihedral) class of the rhombohedral system, possessing the same degree of symmetry as tourmaline Crystals are perfectly developed and are usually prismatic in habit; they are frequently attached at one end, the hemimorphic character being then evident

Monoclinic crystal system
Sphenoidal is also called monoclinic hemimorphic, domatic is also called monoclinic hemihedral, and prismatic is also called monoclinic normal. The three monoclinic hemimorphic space groups are as follows:
a prism with a wallpaper group p2 cross-section
ditto with screw axes instead of axes

Hilgardite
Crystals occur as distorted tabular triangles and are hemimorphic, polytypes exist.
It was named for geologist Eugene W. Hilgard (1833–1916).
